Red Bull won constructors' title in penultimate race of season in Brazil

Seven-time world champion Schumacher looking forward to a better 2011 season

(CNN) -- Seven-time world champion Michael Schumacher has told CNN that the Red Bull team should have already tied up the Formula One drivers' title -- and can only blame themselves for not having done so.

Fernando Alonso is in pole position to win his third crown, this time for Schumacher's former team Ferrari, at the 2010 season finale in Abu Dhabi this weekend.

The Spaniard has an eight-point lead from Mark Webber, with the Australian's Red Bull teammate Sebastian Vettel another seven points off the pace.

The Austrian outfit has already clinched the constructors' title, but Schumacher claims the drivers' battle should not have gone to the final race -- hinting at the widespread reports of tension between Vettel and Webber.

"I guess the main reason why the championship is still open is due to the fact that one particular team has made quite a few errors this year," he said.

"And if you think out of 18 races they took 15 pole positions and still only being second and third in the drivers' championship -- they want to win the championship, yes.

"But that shows a little bit that something has gone wrong somewhere ... not wanting to go into the details. But it's been exciting, and lots of happenings even from other teams -- so let's see what the final race will bring to us."

The 23-year-old Vettel has impressed as the best of a new line of German talent including Williams' Nico Hulkenberg and Schumacher's Mercedes teammate Nico Rosberg.

Add Virgin's Timo Glock and Force India's Adrian Sutil to the mix -- both of whom are still under 30 -- along with Sauber's comparative veteran Nick Heidfeld, and there will be seven Germans on the starting grid at Yas Marina.

"Well the future is very clearly to make step by step the development that we really have initiated this year and take the fruits of it by starting [well] next year," Schumacher said.

"Who knows how quick we can recover from our slightly down performance this year ... whether we can immediately go back into the championship fight next year or it needs a little bit more build-up time and lead time until the year after.

"But I'm pretty sure next year we'll be much more competitive and we should be able to win races."
